Air New Zealand has accepted the boardroom protocols necessary for chief executive Christopher Luxon to take a seat at the Virgin Australia board table.

The protocols took six months to write and attempt to navigate the many conflict of interests between Virgin and its airline shareholders, Air New Zealand, Singapore Airlines and Etihad Airways.

Air NZ spokeswoman Kelly Kilgour said the protocols between Air New Zealand and Virgin Australia had been agreed and had no impact on the timing of Luxon joining the Virgin Australia Board, expected in July.

"Any potential conflicts of interest were dealt with in the protocols," she said in a statement.

Air NZ owns about 25 per cent of Virgin Australia and operates an alliance with the airline on trans-Tasman flights. Fairfax NZ
